In order that the action of the tool and the A further object of the invention is to profunction of its several elements may be readvide an improved construction of turningily understood, reference will be made in the I00 tool having simple and efficient means for first place to the form of bale-band fastener readily shifting the positions thereof upon with which it is specially useful, said form 0 the buckle-plate or winding element of the of bale-band fastener being disclosed in the fastening during the operation of turning aforesaid application. The said bale-band the same into position for being looked upon fastener essentially comprises a flat bucklethe tightened band. plate 1, adapted to turn bodily upon one edge as a fulcrum and provided with a band-receiving eye or opening 2, which receives the lapped ends of the bale-band B, said plate being further provided with apair of parallel holding-arm extensions 3, having terminal hooks 4 projecting laterally from the same side of the plate and cooperating with alocking-key 5, adapted to be passed transversely beneath the band after the plate has been turned bodily upon itself, and the hooks 4 thereof forced beneath the plane of the inner side of the band. Vith this explanation of the special type of bale-band fastener, in connection with which the turning-tool possesses special utility, a comprehensive understanding of the said tool may be readily obtained.

The tool in its general organization coinprises a lever-handle 6, preferably provided at one end with a loop 7, affording convenient means whereby the tool may be suspended from a suitable hanger, if desired. At its opposite end the said lever-handle 6 is extended into an engaging yoke 8, adapted to stride the buckle-plate or winding element 1 of the fastener and to suitably engage therewith for the purpose of turning it bodily, so as to wind the slack of the band thereon. The engaging yoke 8 is preferably formed integral with the lever handle or shank portion 6 and is usually of a U form to facilitate the proper engagement thereof with the haloband fastener and the handling of the tool in shift-ing it from one position to another.

To provide for the bodily turning of the flat buckle-plate or winding element of the fastener upon one edge as a fulcrum, it is of course necessary to provide the tool with suitable fulcrum-points, and this is effected by constructing the engaging yoke 8 at the terminals or extremities of the opposite side arms 9 thereof with inturned fulcrum projections or pins 10, which are disposed in the same transverse plane and are adapted to take over one side of the buckle-plate or winding element 1 contiguous to the edge thereof, constituting the fulcru m-point of the same in its initial turning movement, and in the operation of the tool the said transverselyalined fulcrum projections or pins 10 are designed to maintain substantially the same position at all times until the fastening is effected.

In addition to the terminal fulcrum projections or pins 10 each side arm 9 of the engaging yoke is provided at an intermediate point, preferably somewhat contiguous to the plane of the fulcrum projections or pins, with a pair of spaced inwardlyprojecting bearingstuds 11 and 12, respectively, disposed at opposite sides of the plane of the arm from which they project, and in the preferred construction of the tool (shown in Figs. 1 and 2 of the drawings) the studs 11 and 12 of each side arm are preferably formed at the terminals of short cross-pieces 13, formed integrally with the side arms 9 and extending short distances at opposite sides thereof in order to space the of the tool.

studs 11 and 12 of each pair a suitable distance apart to secure the desired operation The oppositely-located pins 11 11 and 12 12 are arranged in transverse alinement, so as to bear upon the same side of the buckle-plate or winding element 1 at the same time, thus securing a uniform engagement of the tool with the buckle-plate or winding element at opposite sides thereof, whereby the turning strain is evenly distributed throughout the plate or element and an even winding up of the slack provided for.

In the use of the preferred form of the tool it will be understood that the buckle-plate or winding element 1 of the bale-band fastener first has the lapped ends of the bale-band B threaded therethrough, with the laterallyprojecting terminal hooks 4 thereof disposed next to the bale. To effect the proper winding up of the slack, it is necessary to turn the said buckle-plate or winding element 1 bodily fully half of a revolution and slightly more to permit of the insertion of the locking-key 5 beneath the band. To secure this result, the winding-tool is applied and manipulated in the following manner: First, with the buckle-plate or winding element 1 of the fastener in the initial position (shown in Fig. 1 of the drawings) the fulcrum projections or pins 10 are engaged over the outer side of the buckle-plate, contiguous to one edge thereof, and the transverse bearing-studs 11, located at one side of the yoke, are engaged beneath the opposite side of the plate. ing upon the lever handle 6, usually in a downward direction on account of the position of the fastener, the hook ends 4 of the buckle-plate are swung away from the bale and carried toward the portion of the band at the opposite side of or beneath the plate. By this time the lever-handle 6 will have moved through nearly the arc of a half-circle, and it is necessary to move the same farther away from the bale to effect the final turning of the buckle-plate. To accomplish this, the pressure is lightened on the tool, so that the primary bearing-studs 11 may be relieved from the buckle-plate and .the other or secondary bearing-studs 12 passed over the hook ends 4: of the plate and engaged with the then outer side of the plate, as shown in Fig. 2 of the drawings. This will throw the lever-handle 6 out from the band or bale and will permit of the further inward or downward pressure thereof to complete the turning of the buckle plate and cause the forcing of the hook ends 4: thereof beneath the plane of the band, so as to admit of the insertion of the lockingkey 5. After this has been done the tool is raised and slipped off from the buckle-plate at the edge thereof opposite the hook extremi-,

ties 4E.

Modifications of the construction may be resorted to without disturbing thenovel relation of the fulcrum projections 10 and the two pairs of bearing-studs 11 and 12. One of these modifications is shown in Figs. 3 and By now draw- IIO 4 of the drawings and simply consists in having the secondary bearing-studs laterally movable to facilitate a quick engagement with the outer side of the buckle-plate for the final movement. Referring particularly to Figs. 3 and 4 of the drawings, the same reference characters designate the lever-handle, the yoke, and the fulcrum projections or pins, and the opposite pairs of bearing-studs on the side arms 9 of the yoke are designated, respectively, by the reference characters 11 and 12, the studs 11 being the primary studs to engage beneath the buckle-plate during the initial movement and the studs 12 being the secondary studs to engage on the outer side of the buckle-plate during the final movement. In the modification described the studs 11 and 12 maintain the same spaced relation, respectively, at opposite sides of the yoke-arms as they do in the construction already described; but the secondary studs 12 are laterally movable, the same being preferably formed at one end of pivotal carryinglevers 141, arranged at one side of the engaging yoke 8 and pivotally held thereto intermediate their ends by suitable pivots 15. The ends of the carrying-1e vers 14 opposite the studs 12 are extended into handle portions 15, and between the handle portions 15 of the oppositely-located levers let is interposed a bowed holding-spring 16, the extremities of which are rigidly fastened, respectively, to the opposite handle portions 15 to provide means for normally separating said handle portions, and consequently normally holding the secondary bearing-studs 12 in their inwardly-projected positions.

The manner of using the modified form of tool is substantially the same as that already described, excepting that when it is necessary to shift the bearing-studs to move the secondary studs upon the outer side of the buckle-plate the operator simply presses the handle portions ldtogether, thereby withdrawing the secondary studs 12 to a non-interfering position, so that the lever-handle may be swung outwardly to carry the yoke into a plane permitting the studs 12 to spring in- From the foregoing it is thought that the construction, operation, and many advantages of the herein-described. turning-tool will be readily apparent to those familiar with the art without further description, and it will be understood that various changes in the form, proportion, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
